Sports history can be a frustrating business sometimes! The four team photos below are original images from the early days of Scottish sport, but I have not been able to make a cast iron identification of any of them. There are a few clues but it would be great to be able to pin them down for sure, so I would welcome any positive leads. Either post your comments below or send me a message via the contact form. First up is the oldest. This little CDV was taken at the studio of the famous photographer Thomas Rodger in St Andrews and I have little doubt it is the University rugby team from around 1870. The University library holds the Rodger archive, but has nothing to compare to this.

Next, a cricket team from Edinburgh, dating from around the mid 1870s and taken at the studio of Howie Junior. It could be Carlton CC - a fellow historian has told me their colours were six inch blue and white hoops - but the variety of outfits mean it could be someone else, or possible a representative team.

The Edinburgh football team below is also mid-1870s with long white trousers, and helpfully a couple of the players have the initials HFC on their shirt. It is from the studio of Alex Ayton, but it is not Hibernian or Heart of Midlothian - could it be Hanover?

And finally, another Edinburgh rugby or football team which appears to be late 1880s, also taken by Alex Ayton. Most of the 14 players have caps and a large round badge on their shirt, a couple have distinctive faces, but who are they?
